One man has been arrested and another is wanted in the fatal shooting of an alleged drug dealer whose body was found dumped on a north Houston street.

Michael Duran Demas has been charged with capital murder. Authorities said he and another man, who has not been identified, shot and killed 34-year-old Dan Ibarra during a drug deal.

According to court documents filed in the case, Ibarra's ex-girlfriend told police she had arranged a drug deal between him and a man she knew. She said, the documents state, that the man was going to buy a kilo of cocaine from Ibarra.

The documents state she told investigators she and Ibarra met the nephew of the man about 1:20 a.m. on April 17 at an auto repair shop in the 2100 block of Hardy.

She said Ibarra, who was carrying a backpack that is believed to have contained the cocaine, got into a car with the man and told her he would be back shortly. Another person was sitting in the front passenger seat of the vehicle. The three drove away.

A short time later, according to the documents, the woman told investigators that she came across the scene where Ibarra's body was found. The backpack was gone.

Police said investigators later determined that Ibarra had been shot while he was in a silver car with two other men.

His body was then pulled from the car and left on the street. The gunmen sped away.
